Specification of Letters Patent.

Patented Feb. 6, 191?.

Application filed January 14, 1915. Serial No. 2,137.

To all whom it may concern:

Be it known that I, WILBER J. PINE, a citizen of the United States, residing at Oshkosh, county of Winnebago, and State of Wisconsin, have invented new and use ful Improvements in Wire-interlacing Machines, of which the following is a specification.

My i vention relates to improvements in wire coiling, weaving or interlacing machines.

The objects of my invention are to provide efiicient means for controlling the interlacing feeders, whereby their stroke may be increased or diminished at pleasure to interlace one or more than one wire at any given time. Also to provide means whereby wire fabric of any desired width may be produced. Also to provide an improved timing structure, whereby the lengthof the strand may be definitely determined. Also to provide other improvements, whereby machines of this type may be more efiiciently controlled and operated, and whereby one wire may be fed during one interlacing operation in alternation with another interlacin operation, wherein a plurality of wires are fed simultaneously.

In the drawings, Figure 1 is a plan View of a machine embodying my invention, with the table partially broken away to disclose the interlacing wheels and a portion of the actuating and controlling mechanism. Fig. is a side elevation of the same with the is front end elevation, showing the actuating and timing mechanism. Fig. 4 is a sectional view, drawn to a vertical plane cutting the axis of the wire feeding rolls and roll supporting shafts. Fig. 5 is a sectional view, drawn on line wac of Fig. 3. Fig. 0 is detail plan View of the apparatus for manually controlling the interlacing 0peration and cutting off the wire upon the completion of that operation. Fig. 7 is a detail view in elevation, showing a portion of the actuating connections for the interlacing apparatus.

Like parts are identified by the same reference characters throughout the several views.

The operation of weaving or interlacing wire coils to form what is known as woven wire mattress fabric, is performed in my 5 improved machine in the following manner.

Wire withdrawn from a spool at'l passes upwardly and over a guide pulley 2, and then between feeding rollers 3 and 4:, the roller 4 being provided with a groove 5 of suiiicient depth to partially receive the wire withoutpreventing it from being securely gripped by said feeding rollers. These rollers 3 and 4: force the wire through a coiling die 5', which may be assumed to be of any ordinary construction, provided with a helical groove or passage through which the wire is forced by the feeding rollers and thereby guided along a curved line, whereby the wire is helically coiled. The coil continues to rotate during the continuance of the coiling operation resulting from its passage through the die 5. After leaving the die, the coil passes through guide 6, over a set of guiding wheels 7, 8 and 9, which are disposed in diagonal planes across the line of travel of the coil. These wheels are provided with projecting pins 10, and a partial rotation of the wheels in the direction indicated by the arrows in Fig. l, shifts the fabric, 2'. c. the preceding coil or coils, laterally and angularly to 'a point where the extremity of the incoming coil will interlace with one or more of the previously formed coils resting upon the surface of the table 11. The pins 10 not only position and hold in position the previously formed coils, but

other pins on the same wheel guide and hold the incoming coil in position to interlace therewith. The axes of the guiding wheels are preferably below the level of the table 11 and only the upper portions of the wheels project above the surface of the table 11, the table being provided with suitable diagonal slots through which. these upper portions of the wheels may project. This arrangement allows the peripheral projections or pins 10 to move diagonally along the surface of the table for a short distance and then downwardly through the slots. By 10- eating the axial supports of the wheels below the table instead of above it, I am enabled to get these supports and the actuating connections for the wheels out of the way underneath the table, where they will not interfere. with an inspection of the interlacing operation nor with the coils themselves.

'The guiding members 7, 8 and 9 may be actuated from an operating handle 20, which is axially rotatable and operatively connect- ,YV-nenthe handle 20 is swung to rotate the abowedescribed, of guiding the coils.

ed to move with a cam disk 22, which is mounted to oscillate upon stud shaft 23 supported by bracket 21. Cain-disk 22 is provided with an adjustable cam 24, which comprises a bar having slots'25therein and loosely secured to the under surface of the cam diskby's'et'scr'ews 26. The adjust able cam or bar extends tangentially to the hub 230i the cam disk'22, and is provided on one end with a rounded surface 29.

cam disk 22 in the direction indicated by the arrow, cam bar24c 'Wlll be brought into contact with a roller 31 carried by anelbow crank 32, loosely'mounted on shaft 33. The

continued oscillatory movement of the cam disk 22 then causes cam pro1ection'24l to push roller 31 backwardly and oscillate the elbow lover or bell crank 32, and this oscillatory movement will be transmitted to'the e u ng, mbers '7, 8 and 9,tl11'011gl1 link rod 35, lever 36, I pawl 39, ratchet wheel l0, shaft ll, and

liiik 37, swinging arm 38,

pinions 4:2. The rotative movement of the cam-disk 22 islimited by'mutually engaging stop projections 43 on the bracket, and 44,

id/on the disk.

Each of'the pinions 42 is solocated that teeth' engage the projections or pins 10 on one of the-guiding wheels 7, S or 9, said'projections being adapted to perform the functiono'f gear teeth in addition to the function therefore obvious that when the'pinions L2 are'rotated,-as above described, their motion will be communicated to the guiding members or wheels 7,3 and 9, and the degree of inotion thus communicated, will ultimately depend upon the pos tion of the adjustable cam or-cain bar 24, since it is obvious that when cam-bar 24: has moved to a point where its rounded end 29 engages roller 31, it will cease to actuate said roller, since the rounded end 29 of the cam is curved in an are described-from the axis of shaft 23 as a center.

Tovaryth'e length of stroke. of the elbow lev'er-32- a'nd the consequent degree of move- -menttransm1tted to the guiding wheels 7, S

and 9, I provide means whereby a rotary moveinentof the handle 20 may be trans mitted to shifttlie cam bar 24 tangentially of the 'hub 28, thereby causing the curved lever 20 which is-provide'd with a disk 53 which bears againsta disk rigid on the It is' bracket 21". The disk53'is provided with a pin 55, which is adaptedto'engage in any one of a series'of sockets 56 in disk 52 to lock the disks 52 and 53 together. The bandle 20 carries a key 60, which enters a key way in shaft it), which permits an axial movement of hand lever 20 on shaft 49. A

coiled spring 58, within the handle, normally holds disk 53 against disk 52 with pin interlocked. By retracting the handle 2 the key or pini55inay be withdrawn from any socket 56 in'wliich it is engaged,

whereupon the'handlegshaft l9 and pinion 50' maybe rotated until the pin 55 is in position'for registry with another socket 56, with which such pin may then be DGlYfllttGdtO engage. Du ing'this i'otative movement of the handle upon its axis, pinion 50 transmits 'niotionthrough segment 4 7 and lever 45 to change the 'adjustment'of thecambar 24. Suitable gage marks will be employed, whereby the degreeof this'adjustment will be indicated on disks 52 and 53. A key 63,

carried by bracket 21, and'operating in a key-way 64 in shafts-9, locks shaft 49 against axial movement.

After" transmitting motion to the guiding iieinbers 7, 3 and 9, as above described, if the handle 20 is manually released,'1t swings back to normal position under the tension of thes 'aring 70. I Elbow crank 32 and its connectionsthrough link rod 35, are independently returned. to normal position by a coiled spring '71; The guiding members, however, remain in tlie POSltlOll to which they'have beenrotated, since the retractive *movement of elbow lever 32'is not transmitted to the ratchet wheel .l(),"pawl 39 retracting without actuating said ratchet wheel. i e V bztlll disk 22 is provided with one or more dqpressionsor nrtches '75 in its periphery,

which'are adapted to receive a roller 76 carried'by afleveif77, rigidly connected with shaft Shaft 33 extends upwardly through'the hub of bracket 3e and its upper end is connected with a lever 78, which carries a wire cutter 79. The wire cutter is normally in wire cutting position with reference to a shear bar'80,'the latter also serving as a guide for the coil. When the operator starts toswing'lever 20 to the left, and the initial movement of the lever rotates cam disk 22't0 a position'in which roller 76 is forced outwardly from the cam recess or depression 75, this actuates lever 77 and transmits motion through shaft 33 to lever 7 8, thus severing the lastpreviously formed coil or'coils. The lever 20, in its limited movement, and through the several parts herein described, performs all the functions of severing'coils and moving the formed fab- 'ric llltQPOSltlOIl to be-engaged by the succ'eedi ig coil'or coils. The adjustment of camfbar 29 determines the distance the wheels 7 8 and 9 shall rotate by each swing of lever 20 and thus determines the formation or pattern of the fabric, which is being woven, as it is obvious that by adjustment of disk 53 above described, cam bar 29, as adjusted, gives a greater or less throw to the wheels 7, 8 and 9, and thus the wheels can be rotated a distance equal to the space or spaces between one, two, three or four pins as predetermined by the preliminary rotative adjustment of the handle upon its own axis. When the operator releases lever 20 after a swinging operation, the latter swings back to normal position, whereupon roller 7 6 again registers with cam recess 75 and lever 77 returns to its normal position under the tension of springs 85, leaving the previously completed and now severed coil interlaced with the other coils on the table 11 and advanced forwardly and laterally to a position where the next coil will interlace with it. The machine is now started to feed in the next coil, which will interlace with the coil or coils, thus pushed over and held in posi tion by the wheels 7, 8 and 9. The extrem-' ity of the new coil will not follow the curves of the preceding one, owing to the fact that the preceding coil has moved forwardly to a position where the extremity of the new coil will cross its turns and pass through it during each successive rotation.

The coils on the table 11 may be of considerable length. In order that their parallelism may be maintained, I employ a bar 89 which is mounted upon the surface of table 11 and cooperates with the wheels 7, 8 and 9, in pushing the completed coils laterally. This bar is held in a parallel position and is moved laterally upon the table simultaneously with the lateral movement imparted by the guiding rollers 7, 8 and 9, such motion being derived from the laterally projecting arm 32 of elbow lever 32. The motion of the arm 32 is transmitted to the bar 89 through link rod 91, lever 92, bar 93, and bell-cranks 91, connecting bar 93 at intervals with the guide bar 89. The coils also sometimes require to be steadied during the feeding operation. For this purpose I employ a resilient guide 96, having a diagonal projection 97 and adapted to be manually adjusted into greater or less proximity to the rotative guiding member 9.

Power transmitting me0ham'sm.-The feeding-in rolls 3 and 4 are mounted upon shafts 100 and 101 respectively. Motion is transmitted from shaft 101 to the shaft 100 through gear wheels 102 and 103. Shaft 100 is mounted in bearings 105, which are resiliently supported by springs 106, which are suitably socketed in the frame. This allows a slight vertical yielding movement of shaft 100, which may be limited by screws 108, having threaded bearing cap plates 109, within which the bearings 105 slide. Roller 3 may therefore be raised or lowered to increase or decrease the tension on the wire. The roller 3 is also provided with a peripheral ring a mounted upon an annular resilient cushion 6, preferably formed of rubber, thereby allowing a slight yielding movement of the peripheral ring a and allowing the roller to accommodate itself to wire which varies in thickness in different portions thereof.

Shaft 101 is actuated from a driving pulley 112, which may be connected with the shaft by a clutch 113. The clutch operating lever 11d may be actuated to setting position by a cone 115, having sliding key connection with shaft 101 and adapted to be shifted by the elbow crank shifting lever 117. To set the clutch, the lever 117 may be manually actuated from any suitable point, by means of a flexible wire or cable 118 (Fig. 1), which extends over a pulley 119 and downwardly from said pulley with its lower end connected to a rod 120, extending from arm 1.17 of the elbow lever through slot 121 in the frame, as shown in Fig. 4.

When arm 117 has been raised, cone 115 will be shifted to actuate clutch setting arm 114:, and the shifting lever 117 will be locked in this position by a latch 125 pivoted to the frame at 126, and having an upwardly projecting arm which provides a shoulder at 127 to be engaged by a projection 128 carried 0n the inner face of the arm 117 of the shifting lever. The latch yields during this upward movement to allow projection 128 to pass above the rest 127, after which the latch drops by gravity to a position in which it is shown in Fig. 3. When the shifting cone 115 is moved to clutch setting position, the machine may of course be actuated through power applied through the pulley 112, and will continue in operation until latch 125 is actuated to swing the rest 127 out from underneath projection 128 to allow the retraction of the clutch setting cone 115. The latch may be operated manually by means of a handle 130 pivoted to the-frame at 131 and provided with an upwardly projecting arm 132, the motion of which is transmitted to the latch through link 133, I

arm 134, shaft 135, and an arm 136 connected with said shaft and upon which the arm 129 of the latch normally rests. But it is desirable also to provide automatic timing mechanism, whereby the machine will be automatically stopped after a given interval of operation, viz: the interval. required to feed one length of coiled wire along the side of the fabric which is being formed. For

this purpose I mount a rack bar 138 in the frame and provide it with a projection 139, which, when the rack bar is moved to the right from the position indicated in Fig. 3, will contact with the angularly disposed under surface of latch arm 129 .and raise the 14:0 carried thereby, 142 (Fig. 5), and pinion is mounted.

tate d relatively preferably employed. parts are in the position shown 1n Fig. '3,

latch to r'ele'asingposition. Rack bar 138 is :position by a set of expander rings 156 and 157 (Fig. 1), head 158 on stud shaft 151, and a collar 160 which are mounted between a keyed to slide on shaft 151 and bearing against clutch hub 1 12 on which pinion 143 The expander rings 156 and 157 have abutting cam surfaces with a shoulder at 161, and ring 157 has a projecting operating arm 162, whereby it may be reupon ring 156, which has sliding key connection with shaft 151. The

movement of the shoulder 161 upon'the cor responding shoulder or cam projection 163 of ring 156, causes a separation of saidrings, thereby forcing the pinion 143 and clutch 142 inwardly until clutch member 1A2 engages worm wheel 14:1.

The operating arm 162 of the expander is resiliently connected with arm 117 of the clutch setting lever, a coiled spring 167 being Therefore when the worm wheel clutch 142 will be retracted, but if arm 117 is lifted by a pull upon the wire 118 to shift clutch operating cone 115 and set the main clutch 1'13, motion will be simultaneously communicated from arm 117 to expander arm 162, lifting the latter and rotating expander ring 157 relatively to ring 156, thereby setting the worm clutch 142. Then the machine is set in operation, motion will be transmitted from shaft 101,

through the worm 140, worm wheel 141, and

the worm clutch 152, to actuate pinion 143, the latter being fast on the'hub 170 of clutch member 142. The rotation of pinion 1 13 will move the rack bar 138 to the right from the position in which it is shown in Fig. 3, until projection 139 engages and lifts latch arm 129, whereupon elbow mitted to withdraw cone 115 from its operative relation to the cone clutch. During this movement, the downward movement'of arm 117 carries with it expander arm 162.

The initial movement of the latter releases worm clutch 1A2 and allows it to be pushed out of operative position by spring 150. The clutch 1A2 having been rotated against action of spring 149, as soon as released will return to normal and with it rack bar 138 is through reverse action of pinion 143, re-

turned to normal and to the position in which it is illustrated in Fig. 3. The lever 175 and 176 respectively.

'tially identical with that of the rollers 3 crank 117 is per 117 will now be retracted by spring 169 to withdraw cone 115. The machine will now stop and remain at rest until it is again started by pulling upon the wire118, thereby setting the main clutch.

When the knobs are pushed inwardly, as shown in Fig. 4:, these rollers 175 and 17 6 will be loosely supported and therefore in{ operative for feeding wire, but by pulling the knobs outwardly, they will be connected with'the respective shafts for motion transmission. il -here will of course be as many coiling dies 5 as there are sets of feeding 9Q rollers, and where more than one strand of wire is fed, the several strands will be re- 'ceived between successlve pins or projections 10 on the guiding members 7, 8 and 9. These guiding members will be rotated a greater distance where two sets of wire are being simultaneously fed, than will'be the case where'only one wire is fed. This additional movement,however, canbe readily provided forby shifting adjustable cam bar 2 1 on disk 22.
